• When we download, the link is abroad, so the download speed is very slow. This time, we can use a mirror to download the source.

We normally download is this: pip install the package name
using a mirror like this: pip install -i mirror source package names

ex: pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pymysql
